The document discusses emerging technologies in the hotel industry. Mobile apps now allow guests to monitor and control their stay from their phone, including check-in/out and room automation. Some hotels use voice assistants and mobile keys that let guests enter rooms with just their phone. Biometric logins with facial recognition or fingerprints are also being used for room access. Additionally, some hotels are testing robotic assistants to deliver room service, luggage, drinks, and provide information to guests. Finally, a few international hotels are using augmented reality to provide 360-degree room views and help guests check luggage sizes. These technologies are pushing the hotel industry to fully service guests easily while still maintaining a role for human employees.
